SPECIFICATION.

TO ALL PERSONS TO WHOM THESE PRESENTS SHALL COME:

,Be it known that I, SAMUEL G. PIPER, of Lynn, in the county of Essex,and State of Massachusetts, have invented a new and useful or improvedAir-Heating Apparatus for Stores; and do hereby declare the-same to befully described in the following speeifieatioma'nd represented in theaccompanying drawings, of which- Figure 1 is a front elevation of acooking stove, with my invention applied to it.

Figure 2 is a vertical section of the same. I l

In the said drawings, A represents a cooking stove of any ordinary kind,having one ormorefopenings, a, i l

in its top for the reception of one or more boilers, or pans, forheating or steaming articles to be cooked. Bis a hollow base, or vessel,made with a bottom, d, and'to fit upon or into and be supported by oneof the said boiler openings. From the said vessel, 13, a pipe orhollowcolumn, C, ascends to the ceiling of the apartment and opens into thecase D, of a register, E, such register and its case being arranged inthe floor of the apartment next above the one in which the stovemay beplaced. There is an air-hole or passage, 6, made in the lower part ofthe pipe, Chsuch hole having a cover, or damper, c, dul'y applied to it.

The purpose of my invention is to heat the apartment over that in whichthe stove may be situated, and i this will be accomplished by the heatof the fire in the stove being directed against the bottom, d, of thevessel, B; for on such being heated, it will cause a rarefaction of airwithin the pipe, C, to take place. The air so rarefied will pass upthrough the receiver, and cooler air will enter the pipe through thepassage, 6, which in turn being heated will rise up and pass through theregister. The amount of heat which'canibe introduced into an apartmentby this simple apparatus is much greater than most persons wouldimagine. In thiswayjthe waste Heat of the fuel of a; stove, or that notwanted for cooking purposes, may be utilized or employed for warming aroom. I do not, claim the combination of an air-conduit, and a registerapplied to one extremity of it, but- I claim as my invention thecombination and arrangement of the vessel B and the air-conduit C,provided with an air-receiving passage 15, and a register arranged withrespect to it as described, the whole being for application, asexplained, to a stove and to the floor of an apartment over that inwhich the stove may be situated.
